• Functional tests verify the intended operational behavior of the switch by virtue of running frames
through ports or bypass circuitry.
The following procedures are for checking switch-specific components.
To test a port’s external transmit and receive path
1. Connect to the switch and log in as admin.
2. Connect the port you want to test to any other switch port with the cable you want to test.
3. Enter the crossPortTest command with the following operands (this is a partial list. Refer to the
Fabric OS Command Reference Manual for additional command information):
[-nframes count] Specify the number of frames to send.
[-lb_mode mode] Select the loopback point for the test.
[-spd_mode mode] Select the speed mode for the test.
[-ports itemlist] Specify a list of user ports to test.
Example
To test a switch’s internal components
1. Connect to the switch and log in as admin.
2. Connect the port you want to test to any other switch port with the cable you want to test.

Test Name Operands Checks
crossporttest [-nframes count]
[-lb_mode mode][-spd_mode mode]
[-gbic_mode mode] [-norestore mode]
[-ports itemlist]
Functional test of port external transmit
and receive path.
The crossport is set to loopback using
an external cable by default. However,
this command can be used to check
internal components by setting the lb
operand to 5.
fporttest [-nframes count] [-ports itemlist]
[-seed payload_pattern]
[-width pattern_width] [-size pattern_size]
Tests component to/from and HBA.
Used to test online F_Port devices,
N_Port devices, SFPs, and GBICs. Not
supported for SilkWorm 3016 internal
ports 1 through 14.
loopporttest [-nframes count]
[-ports itemlist][-seed payload_pattern]
[-width pattern_width]
Only tests components attached to a
switch that are on a FC-AL.
spinfab [nMillionFrames [, ePortBeg [, ePortEnd
[, setFail]]]]
Tests components to/from a neighbor
switch, such as ISLs, SFPs, and GBICs
between switches.
